Description

Technical Field

[0001] The utility model relates to the technical field related to elevators, in particular to a novel split load-bearing beam of a machine-room-less traction machine-mounted elevator. Background Art

[0002] The traction machine is a major component of the elevator, and the traction machine load-bearing beam is an important component that supports this major component. Due to the structural characteristics of the elevator, the load-bearing beam not only supports the traction machine, but also the entire elevator. The car, load, counterweight, cable, wire rope, etc. are all hung on the load-bearing beam through the traction machine. It can be said that "a thousand pounds are tied to one beam". It bears all the static and dynamic loads of the elevator. It is generally fixed on the civil construction load-bearing beam of the machine room at the top of the elevator shaft. The material used is channel steel or I-beam;

[0003] Chinese patent announcement number CN210001379U discloses a single load-bearing beam for a machine room-less elevator, the main body of which is a single steel beam, and the remaining parts are evenly distributed along the length of the steel beam, avoiding the problem of too many parts in a local area and too large volume. Therefore, the utility model has a small number of parts, is easy to process, and has low cost. More importantly, the overall volume is symmetrical and small, which is very convenient for hoisting and adjusting the position in the shaft. At the same time, the utility model realizes vertical load-bearing through the two ends of the steel beam, and realizes anti-torsion through the base and the mounting plate, so it does not need to be reinforced with concrete, which is very convenient for both early installation and later adjustment. Not only that, the shock-absorbing pad of the utility model is set on the lower side of the steel beam, thereby reducing the distance from the lower end of the steel beam to the roof of the shaft floor, thereby reducing the top floor space and reducing the requirements for the building. In addition, the utility model strengthens the frame bottom plate and the mounting plate through the middle reinforcement plate and the edge reinforcement plate to ensure the structural strength, thereby supporting the design of a single beam. The structure of the two reinforcement plates is optimized for stress distribution, which can reduce the weight with little impact on the structure;

[0004] In the above technology, the reinforcing plate plays a role in reinforcing the frame bottom plate and the mounting plate, but the assembly of the reinforcing plate requires drilling holes or reserving assembly holes at the edge of the elevator shaft, and then installing the screws. The steps are cumbersome and complicated, and the stress concentration in the middle of the load-bearing beam seriously limits the load-bearing capacity. For this reason, the utility model discloses a new split load-bearing beam of a machine room-less traction machine-mounted elevator to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a novel split load-bearing beam of a machine-roomless traction machine-mounted elevator, so as to solve the problem that the reinforcing plate in the load-bearing beam of the traditional machine-roomless elevator proposed in the above-mentioned background technology plays a role in reinforcing the frame bottom plate and the mounting plate, but the assembly of the reinforcing plate requires drilling holes or reserving assembly holes at the edge of the elevator shaft, and then installing with screws, the steps are cumbersome and complicated, and the stress is concentrated in the middle of the load-bearing beam, which seriously limits the load-bearing capacity.

[0006] To achieve the above purpose, the utility model solves the above technical problems as follows:

[0007] A novel split load-bearing beam of a machine-roomless traction machine-mounted elevator comprises an H-shaped member, both ends of the H-shaped member are screwed with assembly seats, both ends of the H-shaped member are slidably connected with reinforcement members, and a distance adjustment component is installed between the H-shaped member and the reinforcement member;

[0008] Among them, the reinforcing member is composed of an I-beam steel plate sliding along the H-shaped member, a bearing plate fixed on the bottom edge of the I-beam steel plate, and a reinforcing plate fixedly connected between the I-beam steel plate and the bearing plate. The reinforcing plate is a right-angled triangle structure, and the bearing plate is arranged in contact with the elevator shaft wall.

[0009] As a further solution of the utility model, the H-shaped component includes two hollow channel steels parallel to each other, two connecting channel steels are fixedly connected between the two hollow channel steels, a plurality of equipment holes are opened in the middle part of the hollow channel steel and the connecting channel steel, and assembly holes are opened at both ends of the hollow channel steel.

[0010] As a further solution of the utility model, grooves are formed on both sides of the I-beam steel plate, and the grooves are adapted to the structure of the hollow channel steels so that the I-beam steel plate slides along the gap between the two hollow channel steels.

[0011] As a further solution of the utility model, the pitch adjustment assembly includes a screw fixed on one side of the connecting channel steel, the outer side of the screw is threadedly connected to a sleeve, the end of the sleeve away from the screw is rotatably connected to a pressure plate, and the pressure plate is in contact with the adjacent I-beam.

[0012] As a further solution of the utility model, two limiting grooves are provided on the upper side of the assembly seat, and threaded holes are provided on the lower sides of the limiting grooves.

[0013] As a further solution of the utility model, the width of the limiting groove is consistent with the width of the hollow channel steel, and the threaded hole is arranged corresponding to the assembly hole.

[0014] As a further solution of the utility model, an extension edge is fixedly connected to one side of the assembly seat, a positioning hole is opened on the extension edge, and a plurality of reinforcement plates are fixedly connected between the side surface of the assembly seat and the extension edge.

[0017] 2.

[0028] The present invention will be further described below in conjunction with the embodiments.

[0029] See also Figure 1-6 The utility model provides a novel split load-bearing beam of a machine-roomless traction machine-mounted elevator, comprising an H-shaped component 1, wherein the H-shaped component 1 comprises two hollow channel steels 11 parallel to each other, two connecting channel steels 12 are fixedly connected between the two hollow channel steels 11, a plurality of equipment holes 13 are provided in the middle of the hollow channel steel 11 and the connecting channel steel 12, and assembly holes 14 are provided at both ends of the hollow channel steel 11;

[0030] Specifically, the H-shaped component 1 is the core of the entire load-bearing beam, bearing the static and dynamic loads of the elevator, including the weight of the car, load, counterweight, cables, wire ropes, etc. The design of the H-shaped component 1 helps to more evenly distribute the stress generated by the operation of the elevator, reduce local stress concentration, and improve the durability and reliability of the overall structure.

[0031] Furthermore, both ends of the H-shaped component 1 are fixed with an assembly seat 2 by screws, one side of the assembly seat 2 is fixedly connected with an extension edge 23, a positioning hole 24 is opened on the extension edge 23, and a plurality of reinforcement plates 25 are fixedly connected between the side surface of the assembly seat 2 and the extension edge 23.

[0032] Specifically, the reinforcement plate 25 of the right-angled triangle structure has stability, and the fixed connection between the reinforcement plate 25, the assembly seat 2 and the extension edge 23 increases the rigidity of the entire structure, making the load-bearing beam more stable and reducing deformation caused by force. The reinforcement plate 25 helps to disperse the force acting on the assembly seat 2 to a larger area, thereby reducing local stress concentration and improving the durability of the structure.

[0033] Furthermore, two limiting grooves 21 are provided on the upper side of the assembly seat 2, and threaded holes 22 are provided on the lower side of the limiting grooves 21. The width of the limiting grooves 21 is consistent with the width of the hollow channel steel 11, and the threaded holes 22 are provided corresponding to the assembly holes 14.

[0034] Specifically, the H-shaped member 1 is erected between two assembly seats 2, the hollow channel steel 11 is embedded in the limiting groove 21, and the long bolt passes through the assembly hole 14 and is threadedly connected to the threaded hole 22, so that the H-shaped member 1 and the assembly seat 2 are connected as an integrated structure, which is easy to assemble.

[0035] Furthermore, both ends of the H-shaped member 1 are slidably connected with a reinforcing member 3, and the reinforcing member 3 is composed of an I-beam steel plate 31 sliding along the H-shaped member 1, a bearing plate 32 fixed to the bottom edge of the I-beam steel plate 31, and a reinforcing plate 33 fixedly connected between the I-beam steel plate 31 and the bearing plate 32, the reinforcing plate 33 is a right-angled triangle structure, and the bearing plate 32 is arranged to fit the elevator shaft wall.

[0036] Specifically, the structure helps to disperse the stress in the middle of the H-shaped member 1, reduce stress concentration, and improve the stability and durability of the structure. The right-angled triangle structure of the reinforcing plate 33 provides additional support for the I-beam plate 31, thereby enhancing the stability of the entire load-bearing beam.

[0037] Furthermore, grooves 311 are formed on both sides of the I-beam steel plate 31, and the grooves 311 are adapted to the structure of the hollow channel steel 11, so that the I-beam steel plate 31 slides along the gap between the two hollow channel steels 11;

[0038] Specifically, the I-beam 31 slides along the H-shaped component 1, providing an adjustable support structure, allowing the H-shaped component 1 to be fine-tuned within a certain range to adapt to different installation conditions. A load-bearing plate 32 is fixed to the bottom edge of the I-beam 31, and the load-bearing plate 32 is arranged in contact with the elevator shaft wall. When the H-shaped component 1 and the assembly seat 2 are connected as an integrated structure, the sleeve 42 in the distance adjustment component 4 is rotated to make the pressure plate 43 contact the I-beam 31, thereby making the load-bearing plate 32 close to the elevator shaft wall. In this way, the stress in the middle part of the H-shaped component 1 can be transmitted to the elevator shaft wall through the I-beam 31 and the load-bearing plate 32, thereby improving the load-bearing capacity of the load-bearing beam. The I-beam 31 is fixedly connected to the reinforcing plate 33, and the reinforcing plate 33 is usually in a right-angled triangle structure. This design can increase the local stiffness of the I-beam 31 and improve the stability of the overall structure.

[0039] Furthermore, a distance adjustment component 4 is installed between the H-shaped member 1 and the reinforcing member 3, and the distance adjustment component 4 includes a screw 41 fixed to one side of the connecting channel steel 12, and a sleeve 42 is threadedly connected to the outer side of the screw 41, and a pressure plate 43 is rotatably connected to one end of the sleeve 42 away from the screw 41, and the pressure plate 43 is in contact with the adjacent I-shaped steel plate 31;

[0040] Specifically, the sleeve 42 is rotated and moved forward along the screw 41, so that the pressure plate 43 can contact the I-beam 31, so that the load-bearing plate 32 fits the elevator shaft wall. When subjected to force, the stress of the H-shaped member 1 is transmitted to the elevator shaft wall along the I-beam 31, the sleeve 42, and the screw 41, which can provide dispersed support.

[0041] The construction steps of the split load-bearing beam of the new machine-roomless traction machine-mounted elevator are as follows:

[0042] Step 1: Place two assembly seats 2 on both sides of the elevator shaft, align the assembly seats 2 with the reserved holes, and insert expansion bolts to fix the position of the assembly seats 2;

[0043] Step 2: embed the I-beam steel plate 31 into the gap between the two hollow channel steels 11 so that the I-beam steel plate 31 can move with the H-shaped member 1;

[0044] Step 3: Install the H-shaped member 1 between the two assembly seats 2, embed the hollow channel steel 11 into the limiting groove 21, and thread the long bolt through the assembly hole 14 and the threaded hole 22, so that the H-shaped member 1 and the assembly seat 2 are connected into an integrated structure;

[0045] Step 4: Rotate the sleeve 42, the sleeve 42 rotates and moves forward along the screw rod 41, and the pressing plate 43 is able to contact the I-beam steel plate 31, so that the bearing plate 32 is in contact with the elevator shaft wall;

[0046] Step 5: Move the traction machine to the middle of the H-shaped component 1, align the traction machine base with the equipment hole 13, and then fix them with screws to form an integrated structure.
